Perhaps these seemingly innocuous words are really the central issue in this whole book (or even books), because this was the sin that led Satan into his separation from God's government. He got puffed up about himself. These people were puffed up about how much they knew.
That is far more important! So what is God saying here? God says that knowledge by itself will not cut it. Knowledge must be joined with love! Love is an action. It is outgoing concern—toward God, and also toward our fellow man.
